dwc power failure

Hey everyone. This is officially my first post. I was wondering if anyone knew how long the roots can stay submerged in nutrient solution without any bubbles in case of a power outage before damage begins to occur. Thanks to anyone who replies.

not long, if they do, the solution will get very stagnet, if you do have a power outage, u better get a hose and start blowing and mixing that shit up, lol

you should be okay for at least 48 hours

Thanks guys.
